    摘要: Disclosed are TNF-related apoptosis-inducing ligand (TRAIL) trimers (TR3) and nucleic acids encoding covalently linked TRAIL trimers. A TRAIL trimer can have greater stability compared to native TRAIL, and can retain the native killing ability of TRAIL. Target specificity of a TR3 can be shown by blocking its activity with soluble death receptor 5 (DR5-Fc). Also disclosed are modified TRAIL trimers and nucleic acids encoding them. These modifications include additional functional domains, such as antibody fragments (scFvs). A TR3 comprising an additional functional domain can allow for cell-specific delivery of the TR3. In some configurations, a modification such as the addition of a functional domain can be stoichiometrically controlled. In some configurations, a modification can be inconsequential with regard to the bioactivity of TRAIL. In various embodiments, a TR3, including a modified TR3, can be a cancer-selective drug. In some configurations, a TR3 that comprises an additional biologically active moiety such as a functional domain of a protein can have fewer off-target toxicities compared to TRAIL alone. In some configurations, a TR3 that comprises an additional biologically active moiety such as a functional domain of a protein can have enhanced killing capacities compared to the moiety alone. In some aspects, TR3 activity can be targeted to an RBC membrane. The inventors disclose TR3-decorated RBCs that target cell killing in a model of pancreatic cancer.

    摘要: A method of ML-EM image reconstruction is provided for use in connection with a diagnostic imaging apparatus (10) that generates projection data. The method includes collecting projection data, including measured emission projection data and measured transmission projection data. Optionally, the measured transmission projection data is truncated. An initial emission map and attenuation map are assumed. The emission map and the attenuation map are iteratively updated. With each iteration, the emission map is recalculated by taking a previous emission map and adjusting it based upon: (i) the measured emission projection data; (ii) a reprojection of the previous emission map which is carried out with a multi-dimensional projection model; and, (iii) a reprojection of the attenuation map. As well, with each iteration, the attenuation map is recalculated by taking a previous attenuation map and adjusting it based upon: (i) the measured emission projection data; (ii) a reprojection of the previous emission map which is carried out with the multi-dimensional projection model; and (iii) measured transmission projection data.

    摘要: An ink jet printer is configured in a hybrid architecture wherein a full width printbar is combined with a partial width color scanning assembly to provide the capability of selectively printing in black only or, alternately, of producing color prints by operating the color scan assembly exclusively. The cost of the hybrid system, when compared to a full width color system using four full width printbars, is greatly reduced. Throughput time is reduced by providing the control circuitry for distinguishing between black only and color operation and selectively controlling the printer mode of operation. The hybrid architecture is particularly useful in a LAN system since it provides a mechanism for balancing the relative color versus black page decomposition speed limitations. Also, the hybrid architecture enables a relatively simple implementation of a checkerboarding technique to suppress banding in output prints.

    摘要: An ink jet module that can be accurately positioned on a carrier includes a channel die and a heater die. The channel die is rectangular and has a top surface, a bottom surface, a first pair of sides, and a second pair of sides. The bottom surface has a number of spaced parallel channels disposed within it. The channels are parallel to the first pair of sides and extend through one of the second pair of sides. The top surface of the heater die is attached to and aligned with the bottom surface of the channel die. At least one pair of alignment features is disposed within and adjacent a side of the bottom surface of the channel die. The alignment features are recessed areas disposed on opposite sides from each other. The alignment features are dimensioned to receive a retainer that secures the ink jet module to a carrier.

    摘要: An electrostatic discharge (ESD) protection device for protecting a high voltage operating circuit having a high voltage input terminal is disclosed. The ESD protection circuit has a substrate, a first diffusion region formed in the substrate connected to the high voltage input terminal, a second diffusion region formed in the substrate connected to ground, a field oxide layer over the substrate having a thickened region extending into the substrate between the first and second diffusion regions, and a drift region formed in the substrate and located between the first diffusion region and the thickened field oxide layer. These regions are so arranged to move the point of avalanche breakdown away from the first diffusion/field oxide interface, so that the avalanche breakdown voltage is lower than that of the protected circuit while simultaneously preventing avalanche included bipolar feedback in the protection device.

    摘要: An integral filter is fabricated by patterning a layer of etch resistant material on one side of a (100) silicon wafer to produce an array of equally spaced, uniformly sized posts or shapes and doping the exposed surface of the wafer by boron ion implant. The dopant is diffused into the wafer while the array of posts of etch resistant material masks the diffusion under them. The size of the posts or shapes determines the undoped areas of the wafer and, thus, the mesh size of the eventually produced integral filter. The wafer is recoated with a layer of etch resistant material and the other side, which was not doped, is patterned to form a plurality of sets of elongated channel vias and reservoir vias, one reservoir via for each set of channel vias. The wafer is orientation dependently etched for a predetermined time period to produce the sets of channel grooves and reservoir recesses, the recesses having a depth of about 75-85% of the wafer thickness, followed by etching of the wafer in an EDP etchant to finish etching the reservoirs through the wafer. The doped silicon area is not etched, so that an integral filter is produced having an arbitrary pore size determined by the size of the posts or shapes patterned initially prior to the diffused doping step.

    摘要: A thermal ink jet printhead is improved by a specific heating element structure and method of manufacture. The heating elements each have a resistive layer, a high temperature deposited plasma or pyrolytic silicon nitride thereover of predetermined thickness to electrically isolate a subsequently formed cavitational stress protecting layer of tantalum thereon. The pyrolytic silicon nitride permits wet chemical or dry plasma etching delineation of the tantalum without deleterious impact on the silicon nitride, while the delineated tantalum can serve as mask for the wet etch delineation of the silicon nitride. Because of the high deposition temperatures, the aluminum electrodes are patterned and passivated last. Such a construction lowers the manufacturing cost and concurrently provides a more durable printhead.

    摘要: A thermal ink jet printhead is improved by using heating element structures which space the portion of the heating element structures subjected to the cavitational forces produced by the generation and collapsing of the droplet expelling bubbles from the upstream electrode interconnection to the heating element. In one embodiment this is accomplished by narrowing the resistive area where the momentary vapor bubbles are to be produced so that a lower temperature section is located between the bubble generating region and the electrode connecting point. In another embodiment, the electrode is attached to the bubble generating resistive layer through a doped polysilicon descender. A third embodiment spaces the bubble generating portion of the heating element from the upstream electrode interface, which is most susceptible to cavitational damage, by using a resistive layer having two different resistivities.
